部署 obconfigserver 时，您可以选择单独部署，也可以和 OceanBase 数据库以及 ODP 一起部署，本文以合并部署为例介绍如何使用命令行部署 obconfigserver，并简单介绍部署 obconfigserver 后如何使用。
组件介绍
ODP
OceanBase Database Proxy，OceanBase 数据库代理，是 OceanBase 数据库专用的代理服务器，简称为 ODP（又称为 OBProxy）。详细信息请参见 OceanBase 数据库代理文档。
obconfigserver
OceanBase Configserver，obconfigserver 可提供 OceanBase 的元数据注册，存储和查询服务。详细信息请参见 ob-configserver。
部署 obconfigserver
本节介绍如何和 OceanBase 数据库以及 ODP 一起部署 obconfigserver。一起部署的情况下，启动成功后该 OceanBase 数据库会被注册到 obconfigserver 中。
说明
单独部署 obconfigserver 时，您只需将 OceanBase 数据库和 ODP 的组件配置信息删去即可。
步骤一：修改配置文件
若您要同时部署 OceanBase 数据库、ODP 和 obconfigserver，只需在部署 OceanBase 数据库和 ODP 的配置文件下新增 ob-configserver 组件信息，并在 OceanBase 数据库和 ODP 的组件下配置依赖 ob-configserver。
创建一个配置文件 config.yaml，该配置文件中各个组件的配置及注意事项如下所示。
用户配置
## Only need to configure when remote login is required user: username: admin # password: your password if need key_file: /home/admin/.ssh/id_rsa # port: your ssh port, default 22 # timeout: ssh connection timeout (second), default 30username为登录到目标机器的用户名，确保您的用户名有home_path的写权限。password和key_file均用于验证用户，通常情况下只需要填写一个。注意
在配置秘钥路径后，如果您的秘钥不需要口令，请注释或者删除
password，以免password被视为秘钥口令用于登录，导致校验失败。OceanBase 数据库
oceanbase-ce: depends: - ob-configserver servers: - name: server1 # Please don't use hostname, only IP can be supported ip: 10.10.10.2 - name: server2 ip: 10.10.10.3 - name: server3 ip: 10.10.10.4 global: # The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field. home_path: /home/admin/observer # The directory for data storage. The default value is $home_path/store. # data_dir: /data # The directory for clog, ilog, and slog. The default value is the same as the data_dir value. # redo_dir: /redo # Please set devname as the network adaptor's name whose ip is in the setting of severs. # if set severs as "127.0.0.1", please set devname as "lo" # if current ip is 192.168.1.10, and the ip's network adaptor's name is "eth0", please use "eth0" devname: eth0 cluster_id: 1 # please set memory limit to a suitable value which is matching resource. memory_limit: 6G # The maximum running memory for an observer system_memory: 1G # The reserved system memory. system_memory is reserved for general tenants. The default value is 30G. datafile_size: 20G # Size of the data file. log_disk_size: 15G # The size of disk space used by the clog files. cpu_count: 16 scenario: htap mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started. rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started. production_mode: false enable_syslog_wf: false # Print system logs whose levels are higher than WARNING to a separate log file. The default value is true. max_syslog_file_count: 4 # The maximum number of reserved log files before enabling auto recycling. The default value is 0. # Cluster name for OceanBase Database. The default value is obcluster. When you deploy OceanBase Database and obproxy, this value must be the same as the cluster_name for obproxy. appname: obcluster root_password: ****** # root user password proxyro_password: ****** # proxyro user password, consistent with obproxy's observer_sys_password, can be empty server1: zone: zone1 server2: zone: zone2 server3: zone: zone3配置文件中各配置项含义可参见 配置文件说明。需要注意的配置项如下：
depends：您需配置 oceanbase-ce 组件依赖于 ob-configserver 组件，否则无法将该 OceanBase 数据库注册到 obconfigserver 中。
appname：用于配置集群的名字，不配置的情况下 OceanBase 数据库无法注册到 obconfigserver 中。
OceanBase 数据库版本为 V4.3.0 或之后版本时，配置文件中若未配置
scenario，obd 会提供交互式选项供用户选择负载类型。
ODP 组件
obproxy-ce: # Set dependent components for the component. # When the associated configurations are not done, obd will automatically get the these configurations from the dependent components. depends: - oceanbase-ce - ob-configserver servers: - 10.10.10.5 global: listen_port: 2883 # External port.

When a depends exists, obd gets this value from the oceanbase-ce of the depends.配置文件中各配置项含义可参见 配置文件说明。您需注意请勿配置
rs_list配置项，否则 ODP 无法获取 obconfigserver 中注册的集群信息。obconfigserver 组件
ob-configserver: servers: - 10.10.10.1 global: listen_port: 8080 # The port of ob-configserver web server_ip: 0.0.0.0 # Listen to the ob-configserver server IP。When you want to listen to the specified IP address,use it. home_path: /home/admin/ob-configserver # The working directory for prometheus. ob-configserver is started under this directory.

The default value is 7 # log_maxbackups: 10 #The number of manager expired ob-configserver.Log. The default value is 10 # log_localtime: true # Switch of ob-configserver.Log naming with localtime. The default value is true # log_compress: true # Compress ob-configserver.Log switch. The default value is true ## vip config, configserver will generate url with vip_address and port and return it to the client ## do not use some random value that can't be connected # vip_address: "10.10.10.1" # vip_port：8080 ## storage config # storage: ## database type, support sqlite3 or mysql # sqlite3: # database_type: sqlite3 # connection_url: "/home/admin/ob-configserver/.data.db?cache=shared&_fk=1" # mysql: # database_type: mysql # connection_url: "$user:$password@tcp($IP:$PORT)/$metadb?parseTime=true"配置文件介绍：
server_ip：ob-configserver 服务访问白名单，默认为0.0.0.0，表示 ob-configserver 所在服务器的所有 IP 都可以访问。vip_address和vip_port：vip_address和vip_port为负载均衡访问地址配置项。若要在servers下配置多个节点，您需使用负载均衡，请在配置好负载均衡后，填写负载均衡地址 IP 与端口。database_type：数据库类型，提供sqlite3与mysql，默认为sqlite3类型，推荐使用mysql类型。connection_url：数据库连接 URL。选择sqlite3类型时默认为$home_path/.data.db?cache=shared&_fk=1；选择mysql类型时，connection_url可以是 OceanBase 数据库，也可以是原生 MySQL。指定的数据库用户需要有 URL 里对应库 DDL 和 DML 的权限，需注意的是，使用 OceanBase 数据库时这里的库名请勿使用 oceanbase 库，否则会提示没有权限。
步骤二：启动 obconfigserver
部署 obconfigserver
[admin@obtest ~]$ obd cluster deploy test -c config.yaml启动 obconfigserver
[admin@obtest ~]$ obd cluster start test输出如下，可以看到 obconfigserver 访问地址的打印信息。

说明
访问信息中的 jq 命令的作用是格式化（美化）shell 命令行下 json 的输出，可通过
sudo yum install jq安装。{ "Code": 200, "Message": "successful", "Success": true, "Data": { "ObProxyBinUrl": "http://10.10.10.1:8080/client?Action=GetObProxy", "ObProxyDatabaseInfo": { "DataBase": "***", "MetaDataBase": "http://10.10.10.1:8080/services?Action=ObRootServiceInfo&User_ID=alibaba&UID=admin&ObRegion=obdv1", "Password": "***", "User": "***" }, "ObRootServiceInfoUrlList": [ { "ObRegion": "obcluster", "ObRootServiceInfoUrl": "http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=obcluster" } ], "Version": "4660b4b1f237893ba1da50a302e4c3e6" }, "Trace": "07a7cac129713d00", "Server": "10.10.10.1", "Cost": 0 }输出中 ObRootServiceInfoUrlList 中包含一起部署的 OceanBase 集群（obcluster）的集群信息，表示该集群已成功注册到 obconfigserver 中。您可再次请求 ObRootServiceInfoUrl 验证 obconfigserver 中是否可以解析出 OceanBase 集群的信息，命令如下。
curl -s 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=obcluster' |jq .输出如下，成功解析出集群中 OBServer 节点的 IP 和端口。

使用 obconfigserver
部署 obconfigserver 后，您可通过修改 OceanBase 集群配置文件或执行 SQL 命令将 OceanBase 集群注册到 obconfigserver 中，通过指定 obconfigserver 地址启动的 ODP 可以访问该 obconfigserver 中注册的所有 OceanBase 集群。
本节介绍如何将 OceanBase 数据库注册到 obconfigserver 中，以及如何通过指定 obconfigserver 地址启动 ODP。
注册 OceanBase 集群
本节介绍如何将 OceanBase 集群注册到 obconfigserver 中，有修改 OceanBase 集群配置文件和执行 SQL 命令两种方式。
修改 OceanBase 集群配置项
执行 SQL 命令
注意
待注册的 OceanBase 集群配置文件需配置
appname配置项，否则配置 config url 后重启会报错。待注册的 OceanBase 集群需是已启动的集群，目前暂不支持配置待启动集群。
您可执行
obd cluster edit-config命令编辑已有集群的配置文件，将 config url 配置到集群中。配置项示例如下：
obconfig_url: 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1'10.10.10.1:8080：obconfigserver 访问地址，此处仅为示例，您需根据实际情况修改。
test1：待注册的 OceanBase 集群的
appname值，此处以 appname 值为 test1 为例，您需根据实际情况修改。
执行
obd cluster reload命令重启集群，此处以部署名为 test1 为例。obd cluster reload test1执行如下命令验证 obconfigserver 中是否注册了该集群的信息。
curl -s 'http://10.10.10.1:8080/services?Action=GetObProxyConfig' |jq .输出如下，ObRootServiceInfoUrlList 中包含 test1 集群信息。
{ "Code": 200, "Message": "successful", "Success": true, "Data": { "ObProxyBinUrl": "http://10.10.10.1:8080/client?Action=GetObProxy", "ObProxyDatabaseInfo": { "DataBase": "***", "MetaDataBase": "http://10.10.10.1:8080/services?Action=ObRootServiceInfo&User_ID=alibaba&UID=admin&ObRegion=obdv1", "Password": "***", "User": "***" }, "ObRootServiceInfoUrlList": [ { "ObRegion": "obcluster", "ObRootServiceInfoUrl": "http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=obcluster" }, { "ObRegion": "test1", "ObRootServiceInfoUrl": "http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1" } ], "Version": "4840ade8a158753aa5b9ea69ba014fc1" }, "Trace": "d4b4b27fae24e7b4", "Server": "10.10.10.1", "Cost": 1 }执行如下命令验证 obconfigserver 中是否可以解析出 OceanBase 集群的信息。
curl -s 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1' |jq .输出如下，成功解析出集群中 OBServer 节点的 IP 和端口。
{ "Code": 200, "Message": "successful", "Success": true, "Data": { "ObClusterId": 1, "ObRegionId": 1, "ObCluster": "test1", "ObRegion": "test1", "ReadonlyRsList": [], "RsList": [ { "address": "10.10.10.4:4882", "role": "LEADER", "sql_port": 4881 } ], "Type": "PRIMARY", "timestamp": 1692699586370950 }, "Trace": "362172a2d5de734c", "Server": "10.10.10.1", "Cost": 1 }
使用 root 用户登录待注册数据库的 sys 租户
obclient -h<IP> -P<PORT> -uroot@sys -p -c -A # example obclient -h10.10.10.4 -P4883 -uroot@sys -p -c -A其中，
IP为连接 OceanBase 数据库的 IP 地址；PORT为连接 OceanBase 数据库的的端口，直连时为mysql_port配置项的值，通过 ODP 连接时为listen_port配置项的值。使用 OBClient 客户端连接 OceanBase 集群的详细操作可参考 通过 OBClient 连接 OceanBase 租户。
执行如下命令查看 obconfig_url 参数的值
obclient> select name,value,svr_ip,svr_port from oceanbase.__all_virtual_sys_parameter_stat where name='obconfig_url';输出如下，表示当前集群没有配置 config url。
+--------------+-------+---------------+----------+ | name | value | svr_ip | svr_port | +--------------+-------+---------------+----------+ | obconfig_url | | 10.10.10.4 | 4882 | +--------------+-------+---------------+----------+执行如下命令配置 obconfig_url
alter system set obconfig_url = 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1';退出集群后验证 obconfigserver 是否可以解析出 OceanBase 集群的信息
curl -s 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1' |jq .输出如下，成功解析出集群中 OBServer 节点的 IP 和端口。
{ "Code": 200, "Message": "successful", "Success": true, "Data": { "ObClusterId": 1, "ObRegionId": 1, "ObCluster": "test1", "ObRegion": "test1", "ReadonlyRsList": [], "RsList": [ { "address": "10.10.10.4:4882", "role": "LEADER", "sql_port": 4881 } ], "Type": "PRIMARY", "timestamp": 1692699586370950 }, "Trace": "362172a2d5de734c", "Server": "10.10.10.1", "Cost": 1 }
启动 ODP
您可使用 obd 新部署一个 ODP，并配置 obproxy_config_server_url 启动，配置文件示例如下：
##Only need to configure when remote login is required
user:
username: admin
# password: your password if need
key_file: /home/admin/.ssh/id_rsa
# port: your ssh port, default 22
# timeout: ssh connection timeout (second), default 30
obproxy-ce:
servers:
- 10.10.10.2
global:
listen_port: 2883 # External port. The default value is 2883.
prometheus_listen_port: 2884 # The Prometheus port. The default value is 2884.
home_path: /home/admin/obproxy
obproxy_config_server_url: http://10.10.10.1:8080/services?Action=GetObProxyConfig
enable_cluster_checkout: false
# observer cluster name, consistent with oceanbase-ce's appname. When a depends exists, obd gets this value from the oceanbase-ce of the depends.
skip_proxy_sys_private_check: true
enable_strict_kernel_release: false
# obproxy_sys_password: # obproxy sys user password, can be empty. When a depends exists, obd gets this value from the oceanbase-ce of the depends.
observer_sys_password: ******** # proxyro user password, consistent with oceanbase-ce's proxyro_password, can be empty. When a depends exists, obd gets this value from the oceanbase-ce of the depends.
obproxy_sys_password: ********
ODP 的详细参数介绍可参见 ODP 参数。
当 ODP 通过 obproxy_config_server_url 配置项启动后，可以使用 ODP 连接注册到 obconfigserver 中的集群。你可以通过如下命令查看 obconfigserver 中注册的 OceanBase 集群信息。
curl -s 'http://10.10.10.1:8080/services?Action=GetObProxyConfig' |jq .
输出如下，从输出中可以看到该 obconfigserver 中已注册 obcluster 和 test1 两个集群，此时通过 ODP 可成功连接这两个集群。

}
删除集群注册信息
您可通过如下命令删去 obconfigserver 中注册的集群信息，此处以删除 test1 集群信息为例。
curl -X DELETE 'http://10.10.10.1:8080/services?Action=ObRootServiceInfo&ObCluster=test1&ObClusterId=1&version=2' |jq .
输出如下：
{
"Code": 200,
"Message": "successful",
"Success": true,
"Data": "success",
"Trace": "caba1209b3a00c56",
"Server": "10.10.10.1",
"Cost": 4
}
再次查看 obconfigserver 中注册的集群信息。
curl -s 'http://10.10.10.1:8080/services?Action=GetObProxyConfig' |jq .
输出如下，可以看到 test1 的集群信息已不存在。
{
"Code": 200,
"Message": "successful",
"Success": true,
"Data": {

常见问题
启动 obconfigserver 时，报错 prepared statement not supported
问题现象
当使用 OceanBase 数据库做 metadb 时，启动 obconfigserver 报错 prepared statement not supported，查看日志如下所示。
2022-11-16T09:52:14.47799+08:00 ERROR [12258,] caller=cmd/main.go:36:func1: start configserver failed: start config server: create configserver schema: sql/schema: reading schema information Error 1235: while parameter _ob_enable_prepared_statement is disabled, prepared statement not supported
[10.10.10.1:2882] [2022-11-16 09:52:14.459102] [YB42AC1EC731-0005EB5F1D83A0A7] fields: args:="[]"
可能原因
在启动 obconfigserver 时，作为元数据库的 OceanBase 数据库未开启 prepared statement 功能。
解决方法
您可通过如下两种方法解决。
方法一：在配置文件里为 obconfigserver 的
connection_url配置项添加上interpolateParams=true，示例如下。connection_url: "user:password@tcp(IP:PORT)/test?parseTime=true&interpolateParams=true"方法二：连接 OceanBase 集群开启
_ob_enable_prepared_statement参数。查询是否开启
_ob_enable_prepared_statement参数。obclient> select name,value,svr_ip,svr_port from oceanbase.__all_virtual_sys_parameter_stat where name='_ob_enable_prepared_statement'; +-------------------------------+-------+---------------+----------+ | name | value | svr_ip | svr_port | +-------------------------------+-------+---------------+----------+ | _ob_enable_prepared_statement | False | 10.10.10.1 | 2882 | +-------------------------------+-------+---------------+----------+ 1 row in set开启
_ob_enable_prepared_statement参数。obclient> alter system set _ob_enable_prepared_statement='True';
通过 ODP 连接 obconfigserver 中注册的集群时报错
问题现象
通过 ODP 连接 obconfigserver 中注册的集群时报错，示例如下。
$ obclient -h10.10.10.2 -P2883 -uroot@sys#cluster -p -Doceanbase -A
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 11
可能原因
ODP 使用配置的查询 OceanBase 数据库的用户和密码无法访问 OceanBase 集群查询数据。
解决方法
您可通过如下两种方法解决。
方法一：执行
obd cluster edit-config命令查看配置文件，您需查看 OceanBase 集群配置文件中的proxyro_password和 ODP 配置文件中的observer_sys_password两个配置项设置是否保持一致。若配置文件中对应配置项不一致，将两者修改统一后根据输出执行对应命令重启，重启后即可通过 ODP 连接该集群。方法二：查询 OceanBase 数据库中是否存在
proxyro用户使用 root 用户登录 OceanBase 数据库的 sys 租户
obclient -h10.10.10.2 -P2881 -uroot@sys -p -Doceanbase -A查看集群中是否有
proxyro用户select user,password from mysql.user;根据输出结果有如下两种处理方法
结果一：集群中无
proxyro用户，执行如下命令创建proxyro用户，并将密码配置为和 ODP 配置文件中observer_sys_password配置项一致create user 'proxyro' identified by '*****';结果二：集群中存在
proxyro用户，执行如下命令修改proxyro用户密码，使其与 ODP 配置文件中observer_sys_password配置项一致alter user 'proxyro' identified by '*****';
